The present article discusses the potential of thermographic analysis in the evaluation of pathological manifestations in building façades. Its use may assist the identification and diagnosis of pathologies by reducing time and cost of these activities. For the application of this technique, the thermal sensor was calibrated, and the tests were performed in two distinct periods of solar incidence. The obtained results from this study demonstrate that the application of the thermographic analysis enables the identification and measurement of hidden pathological manifestations in façade cladding systems, including hard to reach sites, complementing the results of visual inspections and reducing its subjectivity. Keywords: durability; façade; thermographic analysis; nondestructive testing; pathological manifestations.

Potencial da análise termográfica para avaliar manifestações patológicas em sistemas de revestimentos de fachadas. RESUMOO presente artigo discute o potencial da análise termográfica na avaliação de manifestações patológicas em fachadas de edifícios. Seu uso pode ajudar na identificação e no diagnóstico, reduzindo tempo e custos destas atividades. Para colocar em prática esta técnica, foi realizada a calibração do sensor térmico e os ensaios foram realizados em dois períodos diferentes de luz solar. Os resultados obtidos demonstraram que a aplicação da análise termográfica permite a identificação e medir a extensão de manifestações patológicas ocultas em sistemas de revestimento de fachadas, incluindo locais de difícil acesso, complementando os resultados das inspeções visuais e diminuindo a sua subjetividade.

The growing use of Photovoltaic Solar Energy in Brazil, both in power plants and in distributed generation systems, brings with it a series of practical and technical questions that are not limited to the design and project of the systems. Environmental factors and resources related to the use, operation, maintenance, decommissioning and final disposal of the equipment and components that constitute them, should be taken into consideration, so that these systems maintain an adequate performance during their lifespan granting the safety for users, properties and avoid negative environmental impacts. Within the concept of Risk Analysis within the Life Cycle of these systems, the present study addresses a perspective of the growth of the use of Solar Photovoltaic Energy in Brazil and the risks and impacts resulting from the lack of information on how good practices for a maintenance of its facilities, its performance, safety and sustainability of Photovoltaic Solar Power Generation Systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
